Not in use anymore...in HDR

The airsupplyducts to the boiler of unit EC20.
Here on top are the change over valves (with a diameter of a small car) with which we could change over from airsupply by ventilators or the exhaust of the gasturbine (with an oxygenpercentage of appr 16%).
The ladders are meant for manual operation, that was mostly when they malfunctioned :-( ...

But it's a good subject to picture in HDR.

Better in LARGE...
